PUZZLE.

To all whom it may concern:

Be it known that I, KENZO OKAMOTO, subject of the Emperor of Japan, residing at Hempstead, in the county of Nassau and State of New York, have invented certain new and useful Improvements in Puzzles, of which the following is a specification.

This invention relates to puzzles, and aims to provide a novel and amusing puzzle which may be manufactured at a low cost.

The puzzle embodying the present invention is of that general type including a body through which are threaded the ends of cords which are crossed or in some other manner assembled, the object being to separate the cords without detaching them from the body.

For a full understanding of the invention reference is to be had to the following description and accompanying drawings in which Figure 1 is a perspective View of the puzzle embodying the present invention, the same being shown in normal condition. Fig. 2 is a similar View illustrating the first step in working the puzzle. Fig. 3 is a similar view showing the next step. Fig. 4 is a similar view illustrating the final step.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

In the drawings, the puzzle is illustrated as including a body 1 which is flat and may have any desired fanciful outline and may be made of card-board, celluloid, wood, metal, or in fact any material in sheet form. This body 1 is formed, at each side edge, with a pair of openings, those at one side of the body being indicated by the numeral 2 and those at the other side by the numeral 3.

The numeral 4 indicates a cord or like flexible element which is threaded at its ends through the openings 2 and is provided at its said ends with buttons or other suitable stops 5 which prevent the withdrawal of the ends of the cord from the openings 2. A cord 6 is threaded at its ends through the opening 3, and is provided with stops 7 corresponding to those indicated by the numeral 5.

Specification of Letters Patent.

Application filed May 12, 1911.

Patented June a, 1912. Serial No. 626,797.

In the first instance, the cords are interlooped as clearly shown in Fig. 1 of the drawings, and in working the puzzle one or the other of the cords, for example the cord 4, is folded at a point about midway between its ends, and is inserted through one of the openings 3, and through the loop thus formed is passed the stop upon that end of the cord 6 which is threaded through the said opening 8, this being clearly shown in Fig. 3 of the drawings. The loop formed by folding the cord 4: is then withdrawn from the opening 3, and the two cords will be found to have been separated.

It is obvious that in order to prepare the puzzle for a second working, it is only necessary to reverse the operation above described.

Having thus described the invention, what is claimed as new is 1. A. puzzle consisting of a body formed with oppositely located pairs of openings, and a cord or the like threaded at its ends through the openings of each pair, the cords bieing interlooped and provided at their ends with stops,

2. A puzzle consisting of a body with oppositely located pairs of openings, and a cord or the like threaded at the ends through the openings of each pair, the cords being provided at their ends with stops.

3. A puzzle consisting of a fiat body formed with two pairs of openings oppositely located, and a cord threaded at its ends through the openings of each pair, and being provided at their ends with stops.

4:. A puzzle consisting of a flat elongated body formed near each corner with an opening, a cord threaded at its ends through the openings at one side of the body and provided at its said ends with stops, and a cord threaded at its ends through the openings at the other side of the body and provided with stops at its ends, the said cords between their ends being looped.

In testimony whereof, I aflix my signature in presence of two witnesses.
